Device: Gen0b
Registration Number
NCT06169631
Lead Sponsor

Brief Summary

The purpose of the study is to test the effects of brief, low-intensity transcranial focused ultrasound (TUS) on electrophysiological, behavioral, and cognitive markers related to anxiety disorders.

Detailed Description

We will test the effects of TUS on self-reported and clinical anxiety states in healthy participants and in those with diagnosed anxiety disorders. Participants in these studies will receive pulsed TUS to the brain regions of interest. We will test whether multiple doses of TUS lead to larger reductions in mental states related to anxiety in comparison to a single dose of TUS.

Experiment 2bGen0bExperiment 2b will expand on Experiment 2a protocol with multiple visits. Each visit will consist of the same activities as Experiment 2a.
Experiment 1Gen0bThe study will consist of 2 groups. A: no current diagnosis of anxiety or other psychological disorders. B: Current diagnosis of anxiety disorder. Results will be analyzed within and between groups. Participants will answer standardized questionnaires and other similar validated psychological scales. An ultrasound transducer will be placed on their head aimed at the brain region of interest. EEG data will be collected throughout the process. After this process, participants will answer a set of post experiment questions.
